Economist Peter Schiff stated that Elon Musk lost roughly $150 billion on paper Monday after SpaceX shares tumbled, a one-day paper loss larger than Warren Buffett's total fortune, while noting Musk remains the world's only trillionaire. Schiff wrote on X that "SPCX fell 16.5% today. On paper, @elonmusk lost about $150 billion, more than Warren Buffett's entire net worth. However, he's still the world's only trillionaire, so don't feel sorry for him." Forbes estimates Buffett's net worth at about $145 billion. SpaceX closed down 16.43% at $154.60 Monday, extending a multi-day decline, and has shed more than $400 billion in market value, falling to seventh among the world's most valuable companies with a market capitalization of nearly $2.04 trillion. MarketWatch reported that Monday's $400.8 billion decline was the second-largest one-day value loss for a U.S. company. SpaceX also announced a senior unsecured notes offering on Monday and disclosed it had $100.8 billion in cash and cash equivalents as of June 19.
